| Abstract | With the development of heterogeneous networks, small cell is introduced into LTE-A networks to satisfy the demand of user equipments (UEs) with various traffic. Due to the existence of small cells and multi-traffic UEs, traditional mobility load balance (MLB) schemes have not been suitable for the current LTE-A network. By reconfiguring the handover thresholds on the basis of cell load, these algorithms are envisioned to cope with the contradiction between large network capacity demand and shortage spectrum resources. However, the existed algorithms are always focusing on the single traffic which are not efficient for the scenario with non-uniform traffic distribution in small cells. In this paper, we propose a multi-traffic load balance (MTLB) algorithm to balance the traffic load and improve the network capacity with an appropriate handover procedure. In this MTLB algorithm, a novel cell selection method will be executed to improve the quality of service (QoS) of UEs. Moreover, the adaptive adjustment method of threshold and TTT (time to triggering) will be introduced to enhance load balance and reduce the call drop rate. Meanwhile, the simulation results strongly verify that the proposed MTLB algorithm can achieve a good resource utilization and the network throughput can also be improved. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
